There is considerable debate currently about the nature and purpose of fluency. Fluency is much more than remembering isolated facts and routines. It includes students knowing what they can recall readily, being able to use what they know to work out what they do not yet know, and being flexible about adapting this knowledge to unfamiliar situations. Rather than mechanical reproduction, it is preferable that students be able to recall automatically facts and procedures for which they understand both “how” and “why”. This webinar will elaborate these principles and offer a range of classroom experiences to develop such fluency.
